This is a work in progress. I'm doing it on top of this patch serie.

>> Change since V1:
>> * changed the DT representation to use address translation and separate the
>> timings' configuration from the device properties by adding a "simple-bus"
>> inetrmediate node.
>> * moved the smc driver from drivers/bus to drivers/memmory
>> * smc driver now accepts timings in nanoseconds as well as raw register values
>> * smc driver can clip the timings if they're out of bound and dump them to the
>> console
>> * DM9000 timings are now described in nanosecs (for the virtue of example)
>>
>> supported features:
>> * dbgu
>> * nand
>> * lcd
>> * ethernet
>> * leds

>> Jean-Jacques Hiblot (12):
>> at91: dt: Add at91sam9261 dt SoC support
>> at91: dt: sam9261: Basic Device Tree support for the at91sam9261ek
>> at91: dt: sam9261: Added support for the lcd display
>> at91: smc: export sam9_smc_cs_read and sam9_smc_cs_configure.
>> at91: smc: Increased the size of tdf_cycles in struct sam9_smc_config.
>> at91: smc: Adds helper functions to validate and clip the smc timings.
>> at91: dt: smc: Added smc bus driver
>> at91: sam9261: Add a clock definition for the smc
>> at91: dt: sam9261: Pinmux DT entries for the SMC/EBI interface
>> at91: dt: sam9261: Add an entry in the DT for the SMC/EBI bus driver.
>> at91: dt: sam9261: moved the NAND under the smc node
>> at91: dt: sam9261: Added DM9000 in the device tree
